Wow, I can't believe Neal Stephenson of all people writes exclusively by hand. His books are tomes.
I totally buy that this is the case for him. I wonder how much is just what he's used to vs what's actually better. I feel like I write so slow compared to how fast I type that I struggle to put the words together on the paper. I can spurt out something with a keyboard 10x as fast, and then re-review and re-organize and all that.
Knowing that makes a lot of sense. Sometimes his prose can read like a sentence that was started but he’s too much effort in to give up on. It probably helps his writing to do it by hand - you can’t edit quickly on the fly with paper (unless you’re cutting stuff out). I could see this as being part of his process - just write and let the editing happen later.
Whatever the process it is, long as his books may be, it works.
I gave up on the Baroque Cycle, personally, because it felt like it was taking as long to read as it was taking to hand-write.
David Foster Wallace was a longhand manuscript writer too.
The point is to write better, not faster.
I wonder if Brandon Sanderson writes by hand :-D
I wonder if fiction writing at that level is like coding. You can learn to type and navigate really fast, but unless you're working on blub software, if you're doing something interesting and novel, you won't actually get to the goal faster. The bottleneck is the ideas, the structure of the story and the development of the characters, amongst many other concerns.
Speed is the enemy.
If writing by hand is good for your brain (and I suspect it is), the slowness may be part of the reason for that.
